gitmod: add --kim option (keep in memory)
with kim, all objects will be kept in memory. This produces
a great performance improvement.
One simple lousy test on my computer. Serving git's v2.28.0.
Ran this command:
for i in {1..100}; do echo 'tar c mount-point | > /dev/null'; done | time parallel -j 10
- Without kim:
gitmod time:
